Configuring Relational Databases

JNDI: standard Java connection mode. You need to enter the JNDI name.
Spring Cloud Connector: Spring connection mode.

To store application data permanently, you need to use Relational Database Service (RDS). Based on the cloud computing platform, ServiceStage provides RDS for MySQL which is reliable, scalable, easy to manage, and ready for use. RDS for MySQL enables you to easily set and scale relational databases on the cloud. Using the RDS service, you can perform nearly all necessary tasks without programming. This service simplifies operation procedures and reduces routine O&M workloads, so that you can focus on application and service development.

During component deployment, you can bind relational databases in Database. The procedure is as follows: After binding, you can read environment variables upon application running to obtain MySQL information. For details, see Common Environment Variables.

Prerequisites

An RDS MySQL DB instance has been created. For details, see Step 1: Buy a DB Instance.

Procedure

Choose Advanced Settings > Cloud Database.
Click Bind Cloud Database.
Select a cloud database instance that has been bound in the environment and click OK.
If no cloud database instance is bound to the environment, click Add One. On the Edit Environment page that is displayed, click Add Optional Resource to add created RDS resources to the environment.
